How to Cup Coffee According to SCAA Standards

If you’ve ever tried to replicate a professional coffee cupping session at home or in a lab setting, you’ve likely wondered: What exactly counts as ‘correct’ according to industry standards? The Specialty Coffee Association of America (SCAA)—now part of the SCA—developed a rigorous cupping procedure used globally to evaluate coffee fairly and consistently. Whether you’re a roaster, buyer, or barista-in-training, nailing the details ensures your assessments reflect the coffee’s true qualities, not procedural errors.

The SCAA standard cupping protocol specifies using a medium roast, brewed at 8.25g of ground coffee per 150ml of water heated to 93°C, with evaluation taking place within 24 hours after roasting.

What Is SCAA Standard Cupping?

The SCAA (Specialty Coffee Association of America) developed a universal cupping method designed to deliver consistent, repeatable evaluations of brewed coffee. This protocol ensures that coffee professionals—whether buyers, roasters, or cuppers—are assessing flavor, aroma, and body under controlled conditions. The goal is to highlight the intrinsic qualities of the green coffee without variables like brew method or dose distorting the outcome. It forms the basis for green coffee grading, quality control, and cupping competitions worldwide.

Roast Level & Roasting Guidelines

To meet SCAA cupping standards, the coffee must be roasted to a medium level. This corresponds to SCAA Coffee Taster’s Flavor Profile’s roast color reference #55. That means avoiding both underdevelopment and over-roasting: the beans should not appear burnt, scorched, or exhibit any “baking” or focal dark spots. The roast duration must fall between 8 and 12 minutes. Once roasted, the beans need rapid cooling, then storage in an airtight container in a cool, dark place. Importantly, there is an 8-hour “rest” period post-roast before cupping—but no more than 24 hours total. That gives you a window: if your roast finishes at 12:00 noon, cupping must occur between 8:00 PM the same day and 12:00 noon the next day.

Cupping Preparation Timeline

Timing is critical in SCAA cupping. After roasting, let the coffee rest for a minimum of 8 hours, but cup within 24 hours. Once ground, the coffee must be brewed within 15 minutes for optimal freshness—if not possible, cover the grounds and don’t exceed a total of 30 minutes from grind to brew. For consistency, grind enough coffee for 6 cups: 1 for rinsing equipment and 5 for actual cupping. Of those 5, each cup must contain a uniform dose to assess extraction balance. Aim for 70%–75% of particles to pass through a US Standard Size 20 sieve—that’s your target grind size.

The SCAA Cupping Recipe

The SCAA-established ideal cupping formula is simple but precise: 8.25 grams of medium-ground coffee plus 150 milliliters of water heated to 93°C. Let the coffee brew, or “steep,” for 3 to 5 minutes—most cuppers use 4 minutes as the standard. This combination yields a balanced extraction across most cupping bowls. If your cup volume differs—say, it holds 180ml—adjust the dose proportionally (around 9.9g or roughly 10g of coffee). After steeping, break the crust (the floating grounds on top), skim off any residue, and allow the coffee to cool down to approximately 71°C before beginning the sensory evaluation by slurping.

Frequently Asked Questions

What is the official SCAA cupping standard?

The SCAA standard specifies using 8.25 grams of medium-ground coffee per 150 milliliters of water at 93°C, with a brew time of 3 to 5 minutes (typically 4 minutes). The coffee must be a medium roast matching color profile #55 on the SCAA roast color chart, rested for at least 8 but no more than 24 hours post-roast.

How long after roasting can you cup coffee?

SCAA guidelines state that coffee must rest for a minimum of 8 hours after roasting but must be cupped within 24 hours. For example, if roasted at 12:00 noon, cupping must occur between 8:00 PM the same day and 12:00 noon the following day.

What grind size should be used for SCAA cupping?

The grind must be fine enough that 70%–75% of particles pass through a US Standard Size 20 sieve. This equates to a medium-coarse grind tailored for cupping, not espresso or filter.

Can I adjust the coffee-to-water ratio in SCAA cupping?

Yes, but proportionally. The standard is 8.25g coffee to 150ml water. For different cup volumes—such as 180ml—you can adjust to around 9.9g coffee. The key is maintaining balance relative to the volume of water used.

When should I grind coffee for SCAA cupping?

Grind the coffee immediately before cupping, within 15 minutes if possible. If delayed, grind no more than 30 minutes before brewing and keep the grounds covered to preserve freshness.
